On June 25, 2020, The COVID Tracking Project added more than two weeks' worth of probable cases to our **Cases (confirmed plus probable)** for WI, initially causing a large single day increase in cases. We subsequently updated our historical Cases data using data provided to us by the state, which eliminated this one-day increase.In early June of 2020, Wisconsin started reporting probable deaths from COVID-19 separately from confirmed deaths from COVID-19. We did not discover this data until June 29, 2020, and so our time series only has data for this metric beginning on that date. https://www.dhs.wisconsin.gov/outbreaks/index.htm https://www.dhs.wisconsin.gov/covid-19/data.htm https://www.dhs.wisconsin.gov/covid-19/hosp-data.htm @DHSWI https://www.dhs.wisconsin.gov/disease/covid-19.htm People posNeg posNeg Wisconsin 55 false
